Installation, Use and Maintenance
4.11.3. Condensate
removal
Removal to the drains, via a drain hopper, using a P.V.C tube (minimum
diameter 32 mm) is mandatory because the condensates are acidic and thus
aggressive (pH between 3 and 5).
Use a suf
fi
cient slope of 3% to ensure correct
fl
ow of the condensates.
!
WARNING:
Neutralise these condensates before removal according to regulations
in force.
4.12. Gas connection
Before installing the boiler, it is necessary to clean the inside of the installation's
gas line (metallic particles, soldering residue, etc.). This helps to improve the
product's longevity.
Before commissioning the boiler, check that the natural gas supply pressure
corresponds to the boiler's nominal pressure mentioned on the identi
fi
cation
plate.
Before feeding gas to the installation, ensure that the different connections
are correctly made and gas tight.
In particular, check the presence of a removable connector between the
isolating valve and the boiler gas supply tapping.
The value read at the gas valve input must be between the limits indicated in
the table in chapter 2.5, page 11 for the type of gas used.
!
WARNING:
The boiler's gas line connection must not be subject to any mechanical
stress (risk of loss of gas tightness of the gas valve).
Check that the natural gas supply corresponds to the nominal boiler
pressure stated on the identi
fi
cation plate.
4.13. Electrical connection
DANGER:
Ensure that the general electrical power supply has been cut off
before starting any work.
!
WARNING:
Observe the phase polarity - neutral for electrical connections.
!
WARNING:
It is mandatory to connect this boiler correctly to earth and to comply
with applicable standards for low voltage electrical installations in the
United Kingdom.
Provide a two pole circuit breaker upstream of the boiler (distance
between contacts: 3.5 mm minimum).
It is strongly recommended to
fi
t the electrical installation with a
30 mA differential protection.
